SOIL BREAKING AND runvn'mzme MACHINE.

' specification.

My invention is an improvement in soil breakingand pulverizing machines of the type designed to bedr-awn over the field by motive force and having a' plurality of cultivating "implements attached and drawn thereby, one of which, in addition to its action in'breaking'and pulverizing the soil,

acts also as a drag to control the depth of the" cutting of the implements and wherein, in addition to their action in breaking and cultivating the soil,-they act also to propel the machine. r l I i The drawings illustrate preferred forms and adaptations of the invention, however, it is tobe understood that other modifications are contemplated, hence to meet ex 'isting conditions and the different require ments encountered var ous changes in the.

form, proportion "and' minor details within the scope of the invention as claimed, may be resorted to Without departing from the nature thereof.

In the drawings- Figure 1 is a side view of the improved implement;

" Fig. 2 is a perspective view of one of the ing member. p y Corresponding and like parts are referred tom the following description and indicated in the several views of the draw- The invention contemplates a tractor which preferably consists of a' light motor driven truck which may be of any design or construction and embody a motor of any type, preferably of-the internal combustion variety.

In the embodiment of the invention shown in the drawings, the tractor comprises a body or main frame 1 which is supported upon supporting wheels 2, SitlCl support ng wheels being loosely mounted upon an axle 3 which is attached to the body 1 or other convenient part ofthe framework in any desired manner.

The supporting wheels 2 are suitably con- Specification of Letters Patent.

nected to a countershaft 4 whichis transversely disposed with respect to the. body 1 and includes a differential (not shown) and of any preferred type, whereby the two parts of the countershaft may be rotated at different relative speeds. 1 7

As shown, each of the supporting wheels 2 is provided with a gear 6 which is'con- I nected by means of a chain 7' with a spur pinion 8 attached to the outer end of each section of the countershaft. In this manner power is transmitted from the -countershaft 4 to'the supporting wheels.

The motor is arranged within the hood 9 and is connected with the countershaft 4 to Patented Mar. 9, 1920; Application filed August 16, 1917. Serial No. 186,541.

operate the same. A caster frame 26 is journaled at the rear of the frame, and a caster wheel 27 is arranged'withm the frame, to.

Arms 42'connect the shaft 41"with the axle 43 of the wheel 27, thereby maintaining the relationship betweenthe intermesliing spur gears 39 and 40 in any vertical adjustment of the shaft 41; I

A bell crank 44 has one arm connected links 45 with the shaft 41 and the reniaining arm of the bell crank is connected by means of arod 46 with anoperating lever indicated at 46 arranged within convenient reach of the drivers seat so that the shaft 41 may be adjustedvertically as required.

The bell crank [lever is loosely pivoted to 1 allow sufiicient lateral swing of the caster frame. This lever 46 is held in'adjustment by means of latch mechanism engaging a toothed segment 10. 1 p

A second earth treating member A is arranged'between the wheels 2- and the wheel 27, the said element having 'an' axle 14 which carries a spur gear 11 connecte d'by a chain 12 with a spur gear 13 onv theaxle 3.

The shaft 14 is connectedby links 15 with one of the arms 16 of a bell crank. 'lhe bell crank is pivoted on the frame 1 and the other arm has latch mechanism cooperating with a toothed segment 33 on the frame.

The tractor frame 26 is controlled bysuitable operating mechanism connected to the lin'k28at the top of the frame. 7

the machine over the 'field, while the member B pulverizes the soil and retards the The implement or propeller B creates an opposing force acting on the propeller A, causing the said propeller to cut the soil to any de sired depth. Thus this element acts as a brake or as a resistance to apply the opposing force needed to enable earth treating propeller on the shaft 14 to cut as deep or as shallow as circumstances may require.

Each of the propellers or earth treating members Aand B consists of a series of units of the character shown in Fig. 2. Each ofthese units comprises a hub 28 and radial arms 24, the latter having their outer ends 25 curved or deflected in the same direction and tapering or pointed. These devices constitute rotary elements which are strung upon the shafts 1e and 41 and are properly spaced apart and connected to the said shafts in any manner so as to rotate therewith, creating a propelling force. It is proposed to arrange the rotary elements in a progressive series, that is, with the extremities or corresponding arms disposed one slightly in advance of the other so that the ends of t e arms engage the soil in successive ordei rom one end ofthe shaft to the other, thereby obtaining the best results.

From the foregoing taken in connection: 7 with the accompanylng drawings, 1t Wlll be ing devices are also propelling devices, the

wheels 2 being of light construction and being, in fact, supporting wheels and timing wheels that have a reversible action. At times the spikes in the rims of the wheels 2 push backward in order to forcethe shaft 14: tocut through hard ground, or to overcome increased resistance from the soil. This arrangement permits a large amount of weight to be dispensed with. As is known, a motor vehicle depends upon its weight for the propelling force, that is, the vehicle attains weight from gravity. In my construction I utilize the resistance of the soil, and transform it into useful force, tilling the soil and propelling the tractor with .thesame stroke. I use as little weight in the motor and carriage as possible, and the resistance of the soil is also utilized as brakes to regulate the speed of the machine. It is the purpose to create much greater power or force than is needed to propel the light machine with the rotating earth treating propellers; that the extra force may be applied back into the soil for use as brakes, instead of being used to push a heavy tractor over the ground. 'I provide the needed resistance to avoid excessive speed and to equalize the strong propelling force created through the rotating earth-treating propellers.

I claim:

1. In an implement of the character specified, amain frame, a supplemental frame pivotally connected with the main frame to have a caster effect, a tractor wheel mounted in. the supplemental frame, a rotary earth treating propeller connected with the supplementa frame to turn therewith, and a gear connecting the rotary earth treating propeller with the tractor wheel.

2. In an implement of the character specified, a main frame, a. supplemental frame pivoted to the main frame to have a caster effect, a tractor wheel mounted in the supplemental frame, a rotary earth treating propeller, connecting means between the rotary earth treating propeller and supplemental frame to admit of the earth treating propeller having vertical adjustment, gearing between the tractor wheel and rotary earth treating propeller, and means for adjusting the earth treating propeller vertically.

3. An implement of the character specified comprisinga truck frame, supporting wheels for the frame, a motor supported by the frame, a'plurality of rotary earth treatingpropellers supported by the frame, and driving connections between the motor, the wheels and the said propellers for turning the wheels and for turning the propellers and arranged to turn said propellers in opposite directions for the purpose specified, said propellers being vertically adjustable independently of each other.

1. An implement of the character specified comprising a frame, supporting wheels for the frame, a motor supported by the frame, a driving connection between the motor and the wheels, a rotary earth treating propeller supported by the frame and connected to the motor for constraining the said propeller to turn forwardly at a higher rate of speed than that ofthe forward movement of the frame, and means for braking the forward movement of the propeiler to constrain the same to dig into the ground, said means comprising a rotating earth treating element supported by the 7 frame, and a connection between the same and the wheels for turning said element in the opposite direction to the direction of movement of the propeller, said propellers being vertically adjustable independently of each other.
